T 0 all whom it may concern: the invention applied in the operative posi- 55 Be it known that FRED HOLLOMON, a citition to a cross head and related portions of zen of the United States of America, resida locomotive driving gear.

ing at Dunnellon, in the county of Marion Figure 2 is an enlarged longitudinal secand State of Florida, has invented new and tional view of the oil tank or reservoir.

Obviously in the passage of embodiment is shown in the accompanying the oil over the apex of the barrier between drawings, wherein the chambers a limited quantityfinds its Figure 1 is a side view of a lubricating way into the feed ports and is thence conapparatus constructed in accordance with veyed by'suitable conductors consisting for example of the tubes 24- to the oil ducts 26 and '27 which communicate with the bearing surface of the cross head on the guide" bars 12 and 13, and with the bearing 17 of the pitman or connecting rod.

fhus at each stroke" or the cross head; causing a surging of the oil over the Wedge shaped barrier between the oil containing chambers, a certain quantity of oil is depos ited in the feed ports and is thence conveyed directly tothe bearing surf-aces to' maintain them; constantly in a proper condition, whereas when theengine is at rest the supply ofioil is cut off and wastage is avoided.

In the construction illustrated the tank or a reservoir is provided with a removable cover plate 28 secured in place by bolts 29 orthe equivalents thereof, butit will be understood that. the modification as= in this feature to the extent of forming the top ofthe tankintegral with the walls thereof is contemplated, and-in orderto give access to the tank or reservoir in; order that the samemay becharged with oil at suitable intervals, a filling tube 30 is arranged i n communication witht-hesame and is fitted: with a re movable cap 31 having a conical inwardly opening valve 32 vieldingly held seated by aspring 38; and provided with a guide stem 3d,;saidvalv'e beingv displaceable b then'ozzle-or spout of the oil can used 'or, filling the tank; and serving to cut off access to the tank when the filling; operation has been completed so asto exclude dust or other foreign matter, The filling tube is preferably providedwith; a tunnel like cavity 34k into which the oil; may be deposited when the valve 32 is displaced, and; from which it flowsthroughdistributing ducts 35 into the chambers of the tank or reservoir ateither side of the apexuo f the barrier,

Inth'e modified construction illustrated in Figure 5 regulating needle valves 36 are ar ranged in operative relation with seatsfi? at the upper ends of the; feed ports by which oil is conveyed to the bearings,- said valves being provided with grips 89 and being fitted with lock nuts 40, to the end thatthe inlet ends of the feed ports may be throttledto a greater or less extent to avoid the feed-- ing oiithef oil more rapidly than is required to maintain a proper condition of the bearing sufacesi Having described the invention, whatis claimed as, new and useful is:-

1. A lubricator for ,lccomotwe eng ne cross heads conslsting of a tankor reservoirprovided with means for attachment to the cross; head and having terminal oil chambers or compartments disposed in the plane of vibration of the cross head and a barrier separating the chambers and formed; with feed; ports communicating with the bearings to be lubricated; i

2. A lubricator for locomotive engine cross heads consisting of a tank or reservoir provided with means for attachment to the cross head and having terminal oil chambers or compartments disposed in the plane of vibration of the cross head and a barrier separating the cliamb'ers and formed with feed ports communicating with the bearings to be lubricated", said barrier having upwardly convergent walls meeting in the plane or said feed ports. v

3. A lubricator for locomotive engine cross heads having a tank; orreservoir elongated in the direction or movement of the cross head and provided with means for attachment th ereto,,,said tank or reservoir having a double inclinedbottom consisting.
